A novel aromatic amine derivative having an asymmetric structure, and in an organic electroluminescence device which comprises at least one organic thin film layer comprising a light emitting layer sandwiched between a pair of electrode consisting of an anode and a cathode, at least one of the organic thin film layer comprises the aromatic amine derivative singly or as its mixture component. The organic electroluminescence device having an improved success ratio on its production due to difficult cristalization of the amine derivative and exhiviting a longlife time, and also to the aromatic amine derivative for realizing the organic electroluminescence device is provided.
